I wanted to see an example of parallel workflow for prefect, can anyone share me a link of parallel workflows?

In Prefect parallelism can easily be achieved through the use of a Dask executor Example: https://docs.prefect.io/core/advanced_tutorials/dask-cluster.html#the-dask-executor Does this help?

a slightly more complex example?

I welcome anyone to provide a snippet of code if they have a more complex flow they would be willing to share but, still going by the docs, there’s this advanced tutorial https://docs.prefect.io/core/advanced_tutorials/advanced-mapping.html#advanced-features which uses the Dask executor to perform something slightly more complex

can this example be considered as parallel execution?

Yes! When using a dask executor this will be executed in parallel. By default if you do not provide a scheduler

address

to the executor it will create one locally for the run of the flow

providing address to the Dask Executor makes the task run parallely right?

If you have multiple dask workers then it will run tasks in parallel https://distributed.dask.org/en/latest/worker.html

how to set for multiple workers? via cli?

Yes you can, that dask executor tutorial I linked above has a way for doing it via CLI
